LOCOMOTIVE SANDING DEVICE.

SPECIFICATION forming part of Letters Patent No. 652,212, dated June 19, 1900'.

Application filed April 30, 1900.

To all whom it may c0nccrn:

Be it known that I, JOHN CAMPER HOOPER, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Locomotive Sanding Devices, of which the following is a specification.

My invention has for its object to provide improved track-sanding devices for locomotives in which the sand is to be discharged from the sand-box by blasts of air, the quantity of sand to be regulated according to the condition of the rails, and in which the discharge-opening will always be kept free from being clogged by paper or other substance that may be mingled with the sand.

lVith these ends in view the invention consists in the construction, arrangement, and combinations of the parts hereinafter described and claimed.

Reference is to be had to the accom pan yin g drawings, in which Figure l is a horizontal sectional view of a Sandbox of a locomotive, illustrating the arrangement of air-blast pipes, the adjustable sand-nozzles, and the discharge-pipes. Fig. 2 is an elevation of a locomotive sand-box partly broken away to show two of the sanding devices, and Fig. 3 is a vertical sectional view, on a larger scale, of one of the sanding devices shown detached.

Referring particularly to Figs. 1 and 2, A designates the sand-box of a locomotive, in which are placed sanding devices B, O, D, and E, arranged in two pairs, one behindthe other, as shown, in the bottom of the sand box, the devices B O of the front pair each bein g provided with air-blast nozzles and pipes, which latter are connected by a T f with the air-supply pipe F, leading from the cab, the air being under the control of the engineer through the medium of a cook or valve at tached to said pipe, but not shown, while the devices D E of the roar pair are similarly provided with air-blast nozzles and pipes connected with an air-supply pipe F. A pipe G leads from each sanding device laterally through the side of the sand-box A and down to the rails of the track.

Having thus described the general arrangement of the box and sanding devices, I shall Serial No. 14,841. (No model.)

now describe in detail the specific construction of the latter.

Referring particularly to Fig. 3, it will be seen that each sanding devicefor instance, the one designated B--comprises an airchamber H, to which the discharge-pipe G is attached, said chamber being formed with a screwthreaded opening J in its top, in which is a vertically-adjustable inclined sand-nozzle K, formed with a collar 7s, held between two threaded adjusting-sleeves Zand m,which work one inside the other. The outer sleeve on works in the said threaded opening J of the air-chamber, so as to raise and lower the sand-nozzle K in order that its lower end, which is in the air-chamber, may be held in proper relation to the lower side of the said chamber so as to have a space at between the lower end of the sand-nozzle and said lowerside. The sand-nozzle is provided with a spline h, which works in a groove formed in one wall of the air-chamber. The upper end or mouth of the sand-nozzle, which is eX- posed in the sand-box, is flared, as shown. A small air-blast nozzle 0 is fitted in the lower rear side of the air-chamber H in alinement with the dischargepipe G and the space 01 below the sand-nozzle K, said air-blast 11oz zle being connected with one of the air-sup ply pipes F, so that when the engineer causes a blast of air to issue out of the air-blast nozzle the sand will be blown out of the chamber H and through pipe G onto the rails.

It is especially to be noted that the sandnozzle K will readily pass small stones, paper, or other substances which might happen to be mingled with the sand in the box A. It will also be seen that by adjusting the nozzle K up or down the size of the space 01 may be increased or lessened, and thereby the amount of sand deposited on the bottom of the air chamber H ready to be blown out by a blast of air can be readily regulated, and the feed of sand may be shut oflf altogether by lowering the sand-nozzle, so as to bring its end into contact with the bottom of the airchamber.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a locomotive sand box, of an air-chamber provided with a sand discharge pipe; a sand-nozzle opening into said" sand-box and connected with said airchamber and through which the sand passes on its way to the discharge-pipe; means for adjusting the nozzle up or down in the chamber wherebyit may deposit different amounts of sand on the bottom of the air-chamber; and an air-blast nozzle opening into thechamher and arranged to throw blasts of airagainst the sand deposited therein.

2. The combination with a locomotive sandbox, of an air-chamber in said box provided with a discharge-pipe for sand and air and also formed with a threaded opening; a vertically-adjustable inclined sand-nozzle fitted in said threaded opening through which the sand passes to the air-chamber-said sandnozzle being arranged to have its lower end brought into contact with or at varying distances from the bottom of the air-chamber; and an airblast nozzle in said chamber at the rear of said sand-nozzle and in line with the discharge-pipe.

The combination with a locomotives-andbox, of an air-chamber in said box provided with a discharge-pipe for sand and air and also formed with a threaded opening, a sandnozzle in said opening through which the sand passes to the air-chamber, said sand-nozzle being formed with a collar is, a threaded 1 sleeve 'm working in the threaded opening of the air-chamber and engaging the under side of said collar, an inner sleeve Z screwing in. o the outer sleeve and engaging the upper side of the said collar, and an air-blast nozzle in said chamber at the rear of said sand-nozzle and in line with the discharge-pipe.

t. The combination with a locomotive sandbox, of sanding devices therein arranged in pairs one behind the other and provided with air-chambers in which are air-nozzles connected with air-supply pipes leading from the locomotive-cab, discharge-pipes leading from said air-chambers, and vertically-adjustable sand nozzles interposed between the discharge-pipes and air-nozzles, through which the sand passes on its way to the dischargepipes, said sand-nozzles being arranged to be brought into contact with the bottom of the air-chamber to shut off the feed of sand or adjusted above the said bottom whereby to deposit different amounts of sand, and adjusting-sleeves adapted to raise and lower said nozzles.

In testimony whereof I a'liix my signature in the presence of two witnesses.

JOHN CAMPER HOOPER.
